Harp SealsHarp seal numbers have been climbing steadily for years, and hunting of whitecoat pupsonce a cause célèbre of anti-fur activistshas been outlawed in Canada since 1987. But it's still open season after the seals wean at about two weeks old, and more are being hunted now than at any time in the past 35 years. In Canada last year some 286,000 harp seals were harvested, most of which were less than four months old. Is harp seal hunting a sustainable harvest or a senseless slaughter?

China's Growing PainsAs China moves from a planned economy to free enterprise, the developing nation faces a legacy of environmental neglect. With nearly four times as many citizens as the U.S., how would the Chinese cope if the average family in China had two cars, and, like Americans, the average person ate 269 pounds (122 kg) of meat a year?

Share your thoughts on China's growing pains. Enter>>

Some feel their deafness is not a disability that needs to be repaired, but a natural linguistic difference that's given rise to deaf culture. Do you view deafness as an impairment or a linguistic difference? If you were born deaf, would you undergo surgery to enhance your hearing? Enter>>
